While there is no specific diet regime that hypothyroid patients are supposed to follow, they should make sure that they eat a well-balanced diet full of all the nutrients and vitamins that are required by the body. Doctors suggest that eating too much of any food is going to be harmful to thyroid patients. Hence, a generous mix of nutrient-rich fruits and vegetables are going to be helpful for people suffering from hypothyroidism.
Fat is your friend and cholesterol is the precursor to hormonal pathways; if you’re getting insufficient fat and cholesterol, you could be exacerbating hormonal imbalance, which includes thyroid hormones. Natural, healthful fats include olive oil; ghee; avocados; flax seeds; fish; nuts and nut butters; hormone- and antibiotic-free full fat cheese, yogurt, and cottage cheese (yes, full fat, not skim); and coconut milk products.
The first step in treatment of hypothyroidism is to eliminate the effects and causes of the thyroid dysfunction, such as inflammation, overuse of medications, nutrient deficiencies, and changes in hormones due to stress. The hypothyroidism diet eliminates foods that can cause inflammation and immune reactions and instead focuses on foods that help heal the GI tract, balance hormones, and reduce inflammation.
Although relatively low serum T3 levels could contribute to these residual manifestations, the higher serum T4:T3 ratio should also be considered. This has been well-established for 4 decades (28, 50, 59), but only recently has it been recognized as a relevant measure given that higher serum T4 levels will impair systemic T3 production via downregulation of a deiodinase pathway (9). Thus, some emphasis has recently been directed toward establishing the clinical significance of this ratio (1, 5).
Many types of seaweed are chockfull of iodine, but the amount can vary wildly, says Mira Ilic, RD, a registered dietician at the Cleveland Clinic. According to the National Institutes of Health, a 1-gram portion can contain anywhere from 11% to a whopping 1,989% of your percent daily value. But since seaweed is especially high in iodine, you shouldn't start eating sushi every day of the week. Too much iodine can be just as harmful to your thyroid as too little by triggering (or worsening) hypothyroidism. To get seaweed's big benefits without going overboard, Cynthia Sass, MPH, RD, and Health's contributing nutrition editor advises sticking to one fresh seaweed salad per week (in addition to sushi), and steering clear of seaweed teas and supplements.
Lack of ideal thyroid hormone function leads to a global decline in cellular functionality in all bodily systems. The thyroid is a central player in the complex web of human metabolism and is very sensitive to even minor imbalances in other areas of physiology. The thyroid gland is the most common site for the development of an autoimmune disease.
The thyroid gland uses iodine (mostly from foods in the diet like seafood, bread, and salt) to produce thyroid hormones. The two most important thyroid hormones are thyroxine (tetraiodothyronine or T4) and tri-iodothyronine (T3), which account for 99% and 1% of thyroid hormones present in the blood respectively. However, the hormone with the most biological activity is T3. Once released from the thyroid gland into the blood, a large amount of T4 is converted as needed into T3 - the active hormone that affects the metabolism of cells.
Thyroid hormone is critical for normal brain development in babies. Infants requiring thyroid hormone therapy should NOT be treated with purchased liquid suspensions, since the active hormone may deteriorate once dissolved and the baby could receive less thyroid hormone than necessary. Instead, infants with hypothyroidism should receive their thyroid hormone by crushing a single tablet daily of the correct dose and suspending it in one teaspoon of liquid and administering it properly.
*Cassava bears special mention here. You may have heard of it because it is the starchy root vegetable from which tapioca is made, but cassava is also a popular staple food in many Third World countries, where it is eaten boiled, mashed, or ground into flour. Fresh cassava root contains a harmless substance called linamarin, which can turn into hydrocyanic acid (aka cyanide!) when the plant is damaged or eaten. Flaxseeds also contain linamarin. Cyanide is very toxic, so the human body converts it into thiocyanate (which, although it does interfere with thyroid function, is less toxic than cyanide and easier for the body to eliminate).
Seaweed has a high concentration of iodine, an essential nutrient for thyroid function. "Iodine is the precursor for the production of thyroid hormone," Dr. Dodell explains. Seaweed, packaged as nori, wakame, and dulse, can be used in sushi, soups, and salads. Another plus: Seaweed offers nutritional benefits of fiber, calcium, and vitamins A, B, C, E, and K.
Megan Casper, RDN, a dietitian based in New York City and the founder of Nourished Bite, points out that iodine deficiency is the leading cause of hypothyroidism worldwide. This mineral can’t be made by the body, so dietary sources like iodized salt, dairy products, seafood, seaweed, and fortified cereals are important. “Iodine is an essential nutrient in the body, and thyroid hormones are composed of iodine,” explains Rizzo. “Those lacking thyroid hormones may also be lacking iodine.”
